Yeah, me.

Here’s the rule of thumb: do you think the food benefits from being cooked unevenly? For meatballs as you mentioned, I’d sear them in a frying pan to get a little bit of crispiness before I cook them through in the sauce in the microwave. Hunters chicken, cakes, seafood, all good. The microwave will cook far more evenly than a convection oven, though sometimes the unevenness is desirable.
